Google released 46 fixes for Android in its August security patch batch, including one for a Linux kernel flaw in the mobile OS that can lead to remote code execution. While Google never provides much detail in its monthly patch bulletins about how Android flaws are being abused in the wild, it does note that "There are indications that CVE-2024-36971 may be under limited, targeted exploitation."
Google has addressed a high-severity security flaw impacting the Android kernel that it has been actively exploited in the wild. That said, Clement Lecigne of Google's Threat Analysis Group has been credited with reporting the flaw, suggesting that it's likely being exploited by commercial spyware vendors to infiltrate Android devices in narrowly targeted attacks.
